Calcite server supports a minimal set of DDL commands so that you can create a Calcite server with state. However I don’t see us adding a lot of other commands, or supporting other engines’ syntax (which would probably reference concepts that do not exist in Calcite).
So the Babel module is probably a better place for this.
